Abstract:
This paper
presents a new type of gear transmission, the quasi-ellipsoidal
gear transmission with inner-toroidal teeth. According to the
double DOF conjugate surface theory, the function of the
transmission ratio is derived. The pitch surfaces which satisfy
the meshing conditions in the whole meshing zone can be obtained
easily. The tooth profile of the inner-toroidal rotatary
surfaces have high contact strength and can satisfy no pointing
of addendum. This type of transmission is very suitable for the
precise flexible joint of robot.
Key words:
